TITLE: Cryogenic x-y-z Positioner

Requesting Laboratory / Division / Group:

Communications Technology Laboratory Radio Frequency Technology Division Radio Frequency Electronics Group, 672.03

General Statement of Need:

NIST needs a low-power X-Y-Z positioning stage for direct use at 20 mK in a dilution refrigerator with accurate position encoding and a closed-loop controller. The stages must be usable at 20 mK and result in minimal heating of the stage, reducing warmup and keeping the time to cool the temperature of the mixing stage back to 20 mK as short as possible. The materials must be non-magnetic as superconducting circuits sensitive to magnetic fields will be tested.

Current solutions are primarily based on piezoelectric positioners. The power P dissipated in piezoelectric positioners with a capacitance C and loss tangent tan(δ) driven by a sinusoidal signal with frequency f and RMS voltage V in the piezoelectric actuators is given by P = V2 f C tan(δ). If the positioners travel a step size ∆s during each cycle of the sinusoidal drive signal, the total time ∆t to move the positioners a distance d is given by ∆t = d/(f ∆s). Thus, the energy dissipation E required to move a distance d is E = P ∆t = P d/(f ∆s) = V2 C tan(δ) (d/∆s).

To reduce power dissipation at low temperatures to an acceptable level, NIST requires that the energy dissipated in the positioner per unit length of travel E/d = V2 C tan(δ) / ∆s be less than 40 mJ/mm at 4 K for a piezoelectric drive voltage V capable of exerting force of 100 g and drive speed of f ∆s > 0.1 mm/s.

In addition, the power dissipated at the positioner required to determine the position of each encoder must be less than 100 nW and the Z positioners used in the stage must be able to lift 100 g at cryogenic temperatures. Finally, the encoders and closed-loop positioning algorithm must be able to repeatably place each positioner within ±2 um.
